Q: is this memory card compitable with my macbook ?

If your computer is identified correctly, and is considered a MacBook (13-inch Early 2008)

then the specifications should be as follows, according to http://mactracker.ca database.

And if your computer is actually considered a MacBook Pro, several important specs differ.

The following assumes your initial statement is correct, and the MacBook is not a /Pro.

Introduced    February 2008

Discontinued    October 2008

Model Identifier    MacBook4,1

Model Number    A1181

EMC    2242

Order Number    MB402LL/A (White), MB403LL/A (White), MB404LL/A (Black)

White (2.1 or 2.4 GHz) or Black (2.4 GHz), durable polycarbonate

Built-in Memory    None

Maximum Memory    6.0 GB (Actual) 4.0 GB (Apple)

Memory Slots    2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM

Minimum Speed    --

Interleaving Support    Yes

Upgrade Instructions:

• MacBook: How to remove or install memory - Apple Support

{Note Support instructions ^ do not take into account later testing

by qualified third-party reputable manufacturers of RAM, so total

memory upgrade specs are lower in older Support references}

• How to identify MacBook models - Apple Support

• How to identify MacBook Pro models - Apple Support

And Kingston computer RAM generally is not suited for use in several models of

Apple computer that run OS X. Better choices would be found among Crucial.com

or macsales.com vendor web sites. The correct specification is an important detail.

According to macsales.com (OWC) you need to be exacting on identification to be

able to get the correct specification parts for your MacBook4.1, which generally will

use a DDR2 667MHz up to 6GB (1=2GB + 1=4GB total: 6GB) given two RAM slots.

http://eshop.macsales.com/shop/memory/MacBook/DDR2/ memory + hard drive info

(more: http://eshop.macsales.com/memory/maxram )

crucial web page http://www.crucial.com/ offers two methods they say guarantees

a match for the RAM they stock to work with the computer model build you have.

Use the above as a measure of details in voltage and buffer/non-buffer, among other

specification details, if looking to other sources for these RAM chips. Some appear in

places such as amazon affiliate reseller merchants, or auction sites, or qualified Apple

authorized independent service and sales businesses that may service older Macs.

To speed up an older computer with an SSD may consider Mercury line specs at OWC;

Good luck & happy computing!

However if your computer is MacBook (13-inch, Mid 2009) the specs differ:

Maximum Memory    6.0 GB (Actual) 4.0 GB (Apple)

Memory Slots    2 - 200-pin PC2-6400 (800MHz) DDR2 SO-DIMM

Introduced    May 2009

Discontinued    October 2009

Model Identifier    MacBook5,2

Model Number    A1181

EMC    2330

Order Number    MC240LL/A

Initial Price    $999

Support Status    Vintage

So previous information given in my earlier post may be helpful to determine

the exact identification of the hardware model MacBook 13-inch you have...

Same reference sites also have upgrade memory for other models, etc.

http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/Macbook_ selector

The name MacBook does not infer compatibility of any or all replacement

parts across any or all models, so to be sure, you need to double-check.

Once you can positively determine your MacBook build year series model:

http://eshop.macsales.com/memory/maxram can help get the correct RAM.

While you may be able to physically fit faster-spec RAM where slower spec

was officially the correct part, it will not run better or faster, & may cost more.

Good luck in this matter

The short answer is that the RAM specifications you have come up with are incorrect.  The correct specifications for an early 2008 Macbook are:  200-pin PC2-5300 (667MHz) DDR2 SO-DIMM.

Further more, Kingston value RAM has a very poor reputation of compatibilioty with Macs.  The best sources for Mac compatible RAM are OWC and Crucial.

Ciao.

Mac tracker has a different set of specifications for the Mid 2009 MBP:

Ciao.

The reference was not for a MacBook/Pro in my post.

It was direct from MacTracker.ca app in my quad Mini.

However, if the user device happened to be incorrectly

identified, I more than adequately supplied sufficient

links and resources for a braille trail to sleuth more info.

According to MacTracker, the next model up in the

MacBook 13-inch build name, that could use 800MHz

would be the one I quoted their info, for: As a reference.

Were you trying to disparage my reply? Have fun
